"A BV needs to focus on God and lean on Him, with his or her heart open to the leading of the HS. Singing must be sincere, from the depths of one's heart and soul. Of course, there needs to be the anointed touch from God.
A BV's purpose is not just to sing beautifully on stage or create hype. They are there to usher in the presence of God and to build a platform for the preacher to share the Word of God to the congregation. While BVs are not perfect, they are to lead by exemplary lives as a Christian in order to bear a good testimony.
Because you are in the limelight all the time, whatever you are on stage must be who you are after praise and worship."
